coloradoSPEED "LSX" Hydraulic Roller Camshaft, 223/233 | .617/.634 | 109+1 LSA 
Cams specifically designed for 4.8-7.0L LS Series engines to reduce power while stressing the stock valve train beyond GM specifications and exceeding the travel of a stock valve spring. The goal was to maintain rough idle characteristics, too much vacuum pull and bucking-type driveability while decreasing torque and horsepower throughout the RPM range.
Degrees Duration @ .050" Intake/Exhaust: 223/233
Advertised Degrees Duration Intake/Exhaust: 277/287
Lobe Lift Intake/Exhaust: .363/.373
Degrees Lobe Separation: 109+1
Gross Lift Intake/Exhaust: .617/.624

How many people buy the thumpr cams...or talk about buying them. We would all be surprised at the actual number. Take a look at those specs then take a look at these specs.....instead of just reading the description.

Whilst the cam specs look good, unfortunately the description appears to have been a Chinese translation.
Not sure about everyone else but I prefer to purchase a cam that increases power!
